That’s so interesting! Definitely a tactic I’ll try to use from now on. It sounds counter-intuitive but it makes sense when you break it down. A person is more likely to do a favor for someone they like after all; this is just application in reverse. Ben Franklin, once again, proven awesome.
However, I’m wondering if it has the same effect if there’s a power disparity. I like my boss, but if I didn’t and she asked me to do her a favor, I would do it anyway, and probably come out of it feeling the same way towards her. I used to do quite a few favors for people in fast food/restaurant/take-out situations because much of the time, the situation seemed to really call for me to say “yes”, and not all of them increased my affinity towards them. In fact, if they caught me in a poor mood, it would likely degrade my relationship with the asker if we started off neutral, or if I felt I was being handed an unjust responsibility.
Anyway, Ben Franklin Effect!
